void UnifiedAutomation.UaBase.CertificateValidator.RemoveAcceptance ( ICertificate certificate )

inline

Removes the certificate from the list of accepted certificates (does not change the trust list).

Parameters

certificate The certificate.

Implements UnifiedAutomation.UaBase.ICertificateValidator.

virtual void UnifiedAutomation.UaBase.CertificateValidator.Validate ( ICertificate certificate )

inlinevirtual

Validates a certificate.

Parameters

certificate The certificate to validate.

Each UA application may have a list of trusted certificates that is different from all other UA applications that may be running on the same machine. As a result, the certificate validator cannot rely completely on the Windows certificate store and user or machine specific CTLs (certificate trust lists). The validator constructs the trust chain for the certificate and follows the chain until it finds a certification that is in the application trust list. Non-fatal trust chain errors (i.e. certificate expired) are ignored if the certificate is in the application trust list. If no certificate in the chain is trusted then the validator will still accept the certification if there are no trust chain errors. The validator may be configured to ignore the application trust list and/or trust chain.

virtual void UnifiedAutomation.UaBase.CertificateValidator.Validate	(	ICertificate	certificate,
		string	applicationUri,
		string	endpointUrl
	)

inlinevirtual

Validates the specified certificate.

Parameters

certificate	The certificate.
applicationUri	If not null the certificate must contain this URI.
endpointUrl	If not null the certificate hostnames must match this URL.

Implements UnifiedAutomation.UaBase.ICertificateValidator.

virtual void UnifiedAutomation.UaBase.CertificateValidator.Validate	(	ICertificate	certificate,

Parameters

certificate	The certificate.

applicationUri	If not null the certificate must contain this URI.
endpointUrl	If not null the certificate hostnames must match this URL.

Exceptions

System.ArgumentNullException certificate
